Module:Namespace detect/doc

This module allows you to output different text depending on the namespace that a given page is in. It is a Lua implementation of the namespace detect template, with a few improvements: all namespaces and all namespace aliases are supported, and namespace names are detected automatically for the local wiki.

Parameters

 * main - text to return if the page is in the main namespace.
 * talk - text to return if the page is in a talk namespace. This can be any talk namespace - it will match any of "Talk:", "Wikipedia talk:", "User talk:", etc.
 * Subject namespace parameters, e.g. project, user, file... - the text to return if the page is in the corresponding namespace. This module accepts all subject namespaces as parameters, including namespace aliases and virtual namespaces. See below for a list of supported values.
 * other - text to return if no parameters for the page's namespace were specified. This text is also returned if demospace is set to an invalid namespace value.
 * subjectns - if on a talk page, use the corresponding subject page. Can be set with values of "yes", "y", "true" or "1".
 * demopage - specifies a page to detect the namespace of. If not specified, and if the demospace parameter is not set, then the module uses the current page.
 * demospace - force the module to behave as if the page was in the specified namespace. Often used for demonstrations.

Namespace parameters
Possible values for subject namespace parameters are as follows:

Table function
Use the following to display a table with the different possible namespace parameters:

&#123;&#123;#invoke:Namespace detect|table|talk=yes&#125;&#125;

To include the parameter for talk namespaces, use yes.

Porting to different wikis
This module is designed to be portable. To use it on a different wiki, all you need to do is to change the values in Module:Namespace detect/config. Instructions are available on that page.

Technical details
The module uses a data page at Module:Namespace detect/data. This page is loaded with mw.loadData, which means it is processed once per page rather than once per #invoke. This was done for performance reasons.
